COMBINATION-LOCK.

Specficaton of Letters Patet.

Application filed May 5, 1916. Serial No. 95,623.

To all whom it may camera: V

Be it known that I, ALEXANDRE GUINDON, a subject of the King of GreatBritain, and resident of Clarence Greek, in the Province of Ontario,Dominion of Canada, have invented certain new and useful Improvements inCombination-Locks of which the following is the specification.

This invention relates to improvements in conbination locks and theobjects of the in vention are to simplify the Construction of the lockand arrange the several parte so that the combination may be easilychanged, and generally to adapt the several parte to better perform thefunctions required of them.

With the above and other obj ects in view the invention consistsessentially of the improved construction described and set forth in thefollowing specification and accompanyng drawings forming part of thesame.

In the drawings,

Figure l is a front elevation of the improved lock.

Fig. 2 is a lock.

Fig. 3 is an elevation of the lock cover showing the mechanism mountedthereon.

Fig. e is an elevation of the lock with the cover removed to show themechanism.

Fig. 5 is a front elevation of the catch member and latching mechanismmounted on the door.

Fig. 6 is a transverse section on the line 2-2 of Fig. 1.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents the improved combinaton lockoperatively mounted on the door B and jamb post C and comprises thecasing lO designed to house the lock niechansm, access to the casingbeing obtained through the removable cover ll. Rotatably monnted on thecasing lO are a pair of disks'12 and l2 'provided with a plurality ofreference .characters around the periphery the'reof designed to registerwith the characters engraved on the outer face of the casing, and tofacilitate rotating the said disk I provide gripping members 13 mountedthereon.

The disk 12 is provided on the inner face with a stub spindle 14:carrying the pawl 15 eccentrically mounted thereon, the front of backelevation of the improved the pawl slidably cngagng the guide member 16carried by the casing and beingprovided with a reduced point adapted tocoact with the disk 17 Secured to the inner end of the stub spindle 18carried by the disk 12 The disk 17 is formed with a pair of diametrcallyopposite recesses l9 in the periphery thereof, and located between thesaid recesses is a third recess 20 designed, when unlocking the lock toengage with the pawl 15.

If the disk 17 were only provided with the recess 20 it would beextremely easy to open the lock as it would only be necessary to holdthe pa-wl 15 against the edge of the disk and rota-te the same until the,pawl 15 engaged the recess, but by the use of the recesses 19, thiscannot be accomplished as the pawl would engage with either of the saidrecesses before registering with the recess 20, so that the operatormust know the combinaton before he can position the disk 17, relativelyto the pawl 15, so that the point of the said pawl would engage With therecess 20.

The disk 17 is further provided with a keyhole 21 adapted to be engagedby the inner end of a key, which is in the form of a spindle22 slidablyInounted in the casing and provided on its outer end With a grippingmember 23, while intermediate of its` length it carries a disk 2&engaging with the outer face of the leaf spring 25 rigidly mounted onthe outer face of the casing 10.

This leaf spring is inclosed in the casing 26 formed integral with thecasing 10, the casing 26 being provided in the outer wall with aplurality of orifices 27 designed to permit of the characters engravedon the disk 2-3& being readily observed by looking through the saidorifice, thereby permitting of the spindle 22 being rotated to apredetermined position as'indicated by the said characters, so that thepoint of the spindle registers with the keyhole 21 in the disk 17.

"When the inner end of the key or spindle 22 registers with the keyhole21, the spindle 22 is then capable of beingpushed inwardly into thecasing, so that the oint coacts with the resilient looking mem er 28 anddisplaces the same to permit of the keeper member 29 being freedtherefrom to release the looking member and permitting of the door beingthen opened.

eccentrically mounted on the spindle adapted to `engage with therecesses in the recessed disk, a looking member, a keeper membercoacting with the looking member and resiliently controlled meanscomprising a slidably monnted spindle having a crank arm end adapted tooperate the looking member.

2. A combination lock comprisng a casing, a pair of disks rotatablymounted thereon having a plurality of characters around the perpheryadapted to register with characters on the casing, a disk operatvelyconnected to one of the said disks provided with peripheral recesses andhaving a key hole therethrongh, a spindle slidably mounted in the casingprovided with a rednced point adapted to eng-age with the key hole, adisk mounted on the spindle intermediate of its ends, a leaf springeoacting with the disk, a pawl eccentrically mounted on the second saiddisk adapted to engage with the said peripheral recesses, a lookingmember, a manually operated keeper member coacting with the lookingmember, a spndle pro vided with a crank arm slidably mounted on thecasng and adapted to engage with the looking member, a spiral springcoacting with the last said spindle, and means for mannally Operatingthe keeper member.

3. A combination lock comprisng a casing, a pair of disks rotatablymounted thereon having a plurality of characters around the peripherythereof adapted to register with the characters on the casing, a diskoperatively connected to one of the said disks provided With peripheralrecesses and having a key hole therethrough, a spindle having a reducedend coactng with the key hole, a pawl eccentrically mounted on thesecond disk adapted to coact with the said 'ecesses, a looking member, akeeper member coperatng with the looking member, a rack on the keepermember, a pinion cooperating with the keeper member and a manuallyOperating spindle engaging with the said pinion.

In witness whereof I have hereunto set my hand in the presence of awitness.
